THE battle to prevent another devastating flood in York is set to be boosted by a new high=tech early warning station being built upstream.

The Environment Agency is building a new concrete lined channel under the River Nidd near Green Hammerton to ensure accurate ultrasound river flow readings can be taken.

Project manager Oliver Wilson said: “This is one of the agency’s critical assets for our flood warning service and for managing water resource available for abstraction.

“Having an early warning that the Ouse could overtop in York means we can act early to prevent flooding by closing flood gates in the city. The construction under the river enables an ultrasonic device attached under the bridge to measure the exact flow of water coming down the Nidd."
